In 2026 people wired fly connectomes into games, cars and robot bodies. Here they are with their authors, their code and, where it matters, what the method can and cannot show. Below them: experiments built on this site.
The Chrome dinosaur game played by a fly circuit. The readout learned to use the circuit: 99 of 100 test courses completed, 0 of 100 with the circuit silenced.
Fixed 80 neuron MaleCNS circuit with a trained readout
The recipe our training lab follows: fixed circuit, trained readout, silenced control.
An arcade game: try to swat a fly whose escape reflex runs on real wiring, with the circuit lighting up as the swatter approaches.
About 6,000 MaleCNS neurons driving the escape

The September 2026 clip of a fly connectome slicing blocks in Beat Saber, which spread widely.
Fly connectome with a motor readout trained on gameplay
No code or data has been published, so the result cannot be checked. The motor mapping was trained on recorded play, which Patrick Mineault argues makes it hard to say how much the wiring itself contributes (neuroai.science, “Are flies playing Beat Saber?”).

FlyWire connectome
Video only; no code has been published.
The March 2026 demonstration: a whole fly brain simulation walking, grooming and feeding in a physics simulated body.
Complete FlyWire connectome in the NeuroMechFly body
Their simulator is public (eonsystemspbc/fly-brain, GPL 2.0); some claims about the behaviour were debated by researchers.
A 3D fly drives and parks a Mini Cooper, in the browser once you start it locally.
NeuroMechFly v2 body with MuJoCo physics
The public repository contains no connectome data file and no licence, so we could not check how much of the driving comes from wiring.

FlyWire circuits and a MaleCNS brain to leg extract
The research code behind Shiu et al. (2024, Nature). Our neuron model and parameters follow it, and our FlyWire connectivity table comes from it.

Connectome constrained visual system
A toolkit for training vision models whose wiring follows the fly connectome.
Connectome constrained graph networks
The closest existing library of runnable neuroscience models, built on NeuroML. A natural home for exporting our circuits.
Many species and models
A whole brain emulation simulator that can also render what a microscope would see. Our simulated calcium imaging view follows the same idea, and our NES bridge builds any FlyWire circuit from the library inside NES.
Neurons with geometry, virtual calcium imaging and electron microscopy
